Merge tag 'dmaengine-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/dmaengine
Pull dmaengine fixes from Dan Williams: 1/ regression fix for Xen as it now trips over a broken assumption about the dma address size on 32-bit builds 2/ new quirk for netdma to ignore dma channels that cannot meet netdma alignment requirements 3/ fixes for two long standing issues in ioatdma (ring size overflow) and iop-adma (potential stack corruption) * tag 'dmaengine-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/dmaengine: netdma: adding alignment check for NETDMA ops ioatdma: DMA copy alignment needed to address IOAT DMA silicon errata ioat: ring size variables need to be 32bit to avoid overflow iop-adma: Corrected array overflow in RAID6 Xscale(R) test. ioat: fix size of 'completion' for Xen
